Steven Smith's (100 off 42) masterful batting prevented David Warner's (110* off 65) second Big Bash century from succeeding as the Sydney Sixers completed the double victory over Sydney Thunder. The Sixers, relying on Smith, comfortably reached 190 with five wickets and 16 balls remaining. Babar Azam was the first to move the case with two boundaries in the first two overs in front of more than 40,000 people at the SCG. In a sign of things to come, Smith pushed the fifth delivery he faced into the stands. Before Babar rounded the 22-run over with a boundary, Smith introduced Nathan McAndrew into the attack with 6,4,6, the second six being a 107-meter shot that hit the roof of the SCG. With a six-over point in the ninth over, Smith scored 50 off just 23 balls. With two boundaries off Tanveer Sangha, Babar moved into the 40s as the Sixers passed 100 in the 10th over. Chris Green (1/18) bowled a meager two-run over, and Babar received a single from Smith's final delivery. Smith immediately activated the Power Surge after the Sixers took it. Before setting a boundary, he smashed Ryan Hadley for four sixes in a row. The total yield of 32 was the highest in BBL history from the over. After cutting on for 47, Babar fell to McAndrew, who walked off after hitting the boundary cushion. Smith, on the other hand, continued to plunder as he smashed McAndrew for a six and a four to reach 99 while Josh Phillipe was bowled out on the Power Surge's final ball. The Sixers had scored 44 runs in the two overs. Smith reached 100 with his fourth single in BBL history off Sangha, but was stumped on the final ball of the over. He returned to the stage to a standing ovation. The Sixers' middle stutter persisted after Moises Henriques and Sam Curran were cheaply fouled. Jack Edwards and Lachlan Shaw, on the other hand, won the match with three sixes each. With a 15-run outing earlier, Warner welcomed Mitchell Starc back into the Big Bash. He continued his good form by hitting Sean Abbott with three fours. He went one better in the fourth over, and the Thunder went from 49 for 0 after the first four overs to 49 for 49. Starc selected Matthew Gilkes for 12, while Ben Manenti slowed the rate of scoring. Sam Konstas struggled to find any timing in his innings, but Warner hit 50 off 35 balls. He skied one to the 'keeper, ending his laborious 11-ball six. The Thunder needed to move quickly because only 34 runs were scored between overs 6 and 10. However, Sam Billings also struggled and lost to Manenti. The batting team was able to score 38 runs thanks to the Power Surge, which was taken in the 14th and 15th overs. Warner moved into the 80s with a 23-run homer off Abbott, and Nic Maddinson was successful in swinging his willow during his 16-ball stay of 26. In the 18th over, Warner and Maddinson each hit a six, and Warner went on to score a well-deserved century off 61 balls and surpass 400 runs for the season. Curran took three wickets in the final over, leaving the Thunder with 189 for 6 at the end. The Sixers are now fourth in the BBL and will play the Brisbane Heat on Sunday at the Gabba in the final league game to decide who advances to the Finals. Thunder, on the other hand, have only two points from their last league game.
